Example sentences for: chromatid
How can you use “chromatid” in a sentence? Here are some example sentences to help you improve your vocabulary:
Near the end of endo-replication in Spirotrichs many transposons and transposon-like sequences are eliminated by precise excision (Internal Eliminated Sequences or IESs [ 23 ] ). Excision directly precedes massive chromatid fragmentation and de novo telomere formation ("chromosome healing" [ 9 ] ) and the degradation of IESs and of "spacer" DNAs that lie between blocks of sequences destined for different MAC chromosomes.
These include, PDCD6 , a protein that plays a role in T cell receptor-, FAS-, and glucocorticoid-induced cell death [ 11 ] ; TERT , a gene that encodes a reverse transcriptase component of telomerase, dysfunction of which promotes chromosomal instability [ 12 ] ; and TRIP13 , a thyroid hormone receptor interacting protein that binds with the human papillomavirus type 16 (HPV16) E1 protein [ 13 ] . We have identified POLS gene that encodes a DNA polymerase sigma, and plays a role in DNA replication and sister chromatid cohesion at the proximal minimal deleted region [ 14 ] . We performed a semi-quantitative RT-PCR analysis of all four genes ( PDCD6 , TERT , TRIP13 , and POLS ) in eight CC cell lines and did not find evidence for lack of or down regulated expression compared to normal cervix (Fig.
PCS of homologous chromosomes and sister chromatids prior to establishing proper kinetochore-spindle attachment during meiosis I increases the probabilities of both homologues going to the same pole and of equational division of sister chromatids during anaphase I. Upon normal fertilization, MII oocytes with an additional chromosome result in trisomic zygotes; whereas oocytes containing an extra chromatid would be expected to produce 50% trisomic zygotes due to random segregation during anaphase II.
Tetrahymena telomerase and the binder/cutter appear to act concertedly in vivo , as if in a physical complex [ 48 49 ] . However, this contrasts with in vitro properties of the enzyme from exconjugants: 1.) it acts on non-telomeric primers [ 44 50 ] , and 2.) it apparently is no larger than the vegetative enzyme [ 44 ] . Furthermore, telomerase can act in the vegetative MAC of Paramecium , uncoupled from chromatid breakage [ 51 ] . It remains to be seen if a complex between telomerase and binder/cutter activity does exist.
double-strand cutting activity, and thereby explaining coupled action between chromatid cutting and telomere addition (see below).
